Fix buffer_diff for empty buffers

hb_buffer_diff() tweak

I like to have a mode where CONTAINS_NOTDEF and CONTAINS_DOTTEDCIRCLE are not
returned. Abused a value of -1 for that. hb-shape now uses it. Fixes two
of the six tests failing with --verify in test/shaping/run-tests.sh.

We were relying on cluster merges not requiring unsafe flagging because

Speed up buffer variable allocation sanity check

Add HB_NDEBUG
...
API changes:
- If NDEBUG is defined, define HB_NDEBUG
- Disable costlier sanity checks if HB_NDEBUG is defined.
In 1.2.3 introduced some code to disable costly sanity checks if
NDEBUG is defined. NDEBUG, however, disables all assert()s as
well. With HB_NDEBUG, one can disable costlier checks but keep
assert()s.
I'll probably add a way to define HB_NDEBUG automatically in
release tarballs. But for now, production systems that do NOT
define NDEBUG, are encouraged to define HB_NDEBUG for our build.

Right now we cannot test this because it has to be tested using hb-fuzzer.
We should move all fuzzing tests from test/shaping/tests/fuzzed.tests to
test/fuzzing/ and have its own test runner. At that point, should add
test from this issue as well.
